A temperature-sensitive bimetal disc used in refrigerator compressor thermal overload protectors to prevent motor damage by breaking electrical circuits at specific temperatures.
A precision-engineered thermal protection component consisting of two bonded metal strips with different coefficients of thermal expansion. When exposed to temperature changes, the differential expansion causes the disc to snap between convex and concave positions, mechanically opening or closing electrical contacts in compressor protection circuits.

Common failures include material fatigue from repeated cycling, contact welding due to electrical arcing, calibration drift from prolonged high-temperature exposure, and mechanical damage from vibration or improper installation.
Test using controlled heating to verify trip/reset temperatures, measure contact resistance (<50mΩ), check insulation resistance (>100MΩ), and verify snap-action response time. Specialized thermal chambers with precision temperature control are required for accurate testing.
